Serverside chart generator

Does any of you know of a good server-side tool for generating
line-charts - command-line tool will suffice (one that spits out a JPG,
SVG, PNG or such)

Something integrated in Ruby would be even nicer :slight_smile:

Or, maybe you could use something like google charts:

http://code.google.com/apis/chart/

There are some rails wrappers:

http://code.google.com/p/google-charts-on-rails/
http://code.google.com/p/gc4r/http://code.google.com/p/google-charts-on-rails/

or you can just roll your own fairly easily. Whether you can generate/
reference such google charts in your app in real-time by the client's
browser or pre-fetched and stored on the server depends on your app
needs/usage.
